Abstract: In the current situation, air may not seem like anything at all. Here the wind is moving air, as we all know that earth having an even surface, hence sunrays reach earth with different intensity at different part of the surface which creates uneven heating o earth surface, which is causes the differences in the atmospheric air pressure which causes wind, and the kinetic energy of these air is called as wind energy. The mechanical system, which converts kinetic energy available in this atmospheric air in to the required form of mechanicals energies is called is called as wind turbine. So we focused on the like Pole Magnets repulsion characteristics of permanent magnets. These natural properties of magnetic propelling are used as sources of energy. Hence our VAWT system will operate with the, add on features like, magnetic repulsion. When this natural properties is used as source of energy in VAWT, will create the repulsive force which will add some sorts of kinetics energies to the wind turbines, when transferring kinetics energies of wind power into required form of mechanical power. Hence our PM-Propelled VAWT is able to work in the lower wind velocity conditions also. Here our choice is to compare the Permanent magnet propelled VAWT efficiency with its counterpart traditional VAWT.
